1. Imaging of the acute scrotum: is there a place for contrast-enhanced ultrasonography?
Purpose: To present and evaluate the findings of contrast-enhanced ultrasonography (CEUS) in typical cases of acute painful scrotum. Materials and methods: Nineteen patients aged from 19 to 61 years old were included in the study. All patients underwent grey-scale and color Doppler ultrasonography (US) of the scrotum, followed by imaging after i.v. administr

2. Studies about the loading of monoethanolamine (MEA) onto the non-ionic Amberlite XAD-7 resin for retention of S(IV) species / Estudos da modificação da resina não-iônica Amberlite XAD-7 com monoetanolamina (MEA) para retenção de espécies de S(IV)
A monoetanolamina (MEA) é um composto bifuncional pertencente à classe dos amino-álcoois, muito utilizado em processos industriais envolvendo a remoção de gases ácidos como SO2 , CO2 e H2S. A resina Amberlite XAD-7 é uma resina não-iônica de polaridade intermediária muito utilizada em procedimentos de pré-concentração de compostos orgânicos e �

3. Development of catalytic methods for determination of sulphur dioxide in the environment / Desenvolvimento de métodos catalíticos para determinação de dióxido de enxofre no meio ambiente
As formas SO2, HSO3- e SO32- em meio aquoso, são espécies de enxofre (IV) que coexistem; suas concentrações no equilíbrio químico dependem do pH do meio. O estudo das oxidações do S(IV) encontrado na atmosfera, resultante de fontes naturais e antropogênicas, é de fundamental importância, pois os produtos formados têm caráter ácido. Como consequ

4. Sulphur bath and mud pack treatment for rheumatoid arthritis at the Dead Sea area.
Forty patients with classical or definite rheumatoid arthritis in a stage of active disease were treated for two weeks at a spa hotel. The patients were divided into four groups of 10. Group I was treated with daily mud packs, group II with daily hot sulphur baths, group III with a combination of mud packs and hot sulphur baths, and group IV served as a cont

5. Transport of proteins to the mitochondrial intermembrane space: the 'sorting' domain of the cytochrome c1 presequence is a stop-transfer sequence specific for the mitochondrial inner membrane.
The presequence of yeast cytochrome c1 (an inner membrane protein protruding into the intermembrane space) contains a matrix-targeting domain and an intramitochondrial sorting domain. This presequence transports attached subunit IV of cytochrome c oxidase into the intermembrane space (van Loon et al. (1987) EMBO J., 6, 2433-2439). In order to determine how t

6. Changes in the bronchial reactivity of dogs caused by exposure to sulphur dioxide.
The effects of a 2 h exposure to 250 and 400 p.p.m. of SO2 delivered via an endotracheal tube on the reactivity of the dog lung have been studied. Forty-eight hours after exposure to 250 p.p.m. SO2 base-line values of total lung resistance and dynamic lung compliance were unchanged but there was an increase in the bronchoconstrictor response to histamine (20

7. Pyloric reconstruction for severe vasomotor dumping after vagotomy and pyloroplasty.
The performance of vagotomy and pyloroplasty is followed by the occurrence of dumping symptoms in 10-30% of patients. In a few, these are severe, persistent, and refractory to dietary and medical management. Pyloric reconstruction was performed in nine patients with severe dumping symptoms. All patients were treated conservatively for at least 1 year before
